Audio Jack Interface Solution with Moisture Sensing

Features

Description

Detection:

The FSA8039A is a detection switch for an audio jack

that employs normally open detect pin. The

Accessory Plug-In

FSA8039A works with 3-pole and 4-pole accessories.

The FSA8039A features moisture sensing that prevents

false detection of accessories in the audio jack. The

integrated MIC switch allows a processor to configure

attached accessories. The architecture is designed to

allow common third-party headphones to be used for

listening to music from mobile handsets, personal media

players, and portable peripheral devices.
